MP/H Rules/Histology--Thyroid: Is a "papillary carcinoma of the thyroid" coded to 8260/3 [Papillary adenocarcinoma] per the ICD-O-3 because it lists "papillary carcinoma of the thyroid" as a synonym for that code or should it be coded to 8050 [Papillary carcinoma, NOS]?
For cases diagnosed 2007 or later, assign code 8260 [papilary carcinoma of the thyroid].
Surgery of Primary Site--Breast: Should code 51 (Modified radical mastectomy without removal of uninvolved contralateral breast) be used when a patient has excisional biopsy (22) and axillary dissection followed by a simple mastectomy without removal of uninvolved contralateral breast (41) as part of the first course of treatment?
Assign code 51 or 52 if a patient has an excisional biopsy and axillary dissection followed by a simple mastectomy during the first course of therapy. Code the cumulative result of the surgeries, which is a modified radical mastectomy in this case.
SEER collects only one surgery code per case. Code the most invasive, extensive or definitive surgery in Surgery of Primary Site.
Multiplicity Counter-Breast: The general instructions say to ignore separate microscopic foci when determining when to use the single tumor or multiple tumor modules. Do these instructions apply if sizes are given for the foci? See Discussion.
For instance, would a 1.2 cm breast tumor with 3 scattered microscopic foci ranging from 2-4 mm be treated as multiple tumors (4), or as a single tumor?
If the microscopic foci are measured and listed as part of the diagnosis, they should be counted as multiple tumors.
MP/H Rules/Multiplicity Counter--Lung: If metastatic tumors are not counted in this field, should the multiplicity counter be coded to 01 for a case with a primary left lower lobe of lung tumor with a satellite tumor in the left upper lobe?
For cases diagnosed 2007-2013:
No, code multiplicity counter to 02 [two tumors present]. According to the multiple primary rules, these two lung tumors are reported as a single primary. Record the number of tumors reported as a single primary in Multiplicity Counter.
Multiplicity Counter no longer required by SEER as of 1/1/2013.
Type of Multiple Tumors--Lung: Is this field coded to 40 [Multiple invasive] or 80 [Unk in situ or invasive] when only one nodule is biopsied of multiple existing nodules for a reported single lung primary? See Discussion.
The right lung has 4 tumor nodules in the upper lobe. Biopsy of one tumor is positive for moderately differentiated adenocarcinoma. No other work up performed.
Should code 40 be used because we dont know the behavior of the other nodules?
The best code to use in this case is 40 [multiple invasive]. For lung only, it is assumed that all of the tumors are the same histology and that all are invasive.
MP/H Rules/Multiple Primaries/Histology--Prostate: How many primaries should be abstracted and how should the histology field(s) be coded for a case in which the pathology specimen showed adenocarcinoma in 20% of the tissue and sarcoma in 50% of the tissue? See Discussion.
Patient has TURP. The final path diagnosis is adenocarcinoma in 20% of tissue and sarcoma in 50% of tissue.
Because it is unknown whether there is a single or multiple tumors, rule M1 (Other Sites) is used which states the case is to be abstracted as a single primary.
Single invasive histology rules are followed to rule H16, but table 2 does not contain a mixed code for this situation, even though ICD-O-3 has a code 8933/3 for "adenosarcoma". Therefore, rule H17 is applied that states to use the highest code, which in this case would be 8800/3 [Sarcoma, NOS]. Is this correct?
For cases diagnosed 2007-2014, code as two primaries, one adenocarcinoma and the other sarcoma.
This is two tumors (adenocarcinoma and separate sarcoma) until proven otherwise. Do not code as adenosarcoma, as this is a gyn-specific diagnosis. Adenosarcoma of the prostate is not a recognized entity in the WHO classification of prostate tumors.
Histology--Hematopoietic, NOS: If an initial bone marrow diagnosis is "...more compatible with CMML/MPD" and within three months the final diagnosis per the oncologist is "MPD/CMML with acute myeloid leukemia transformation," is histology coded to CMML or AML? See Discussion.
09/06 BM Bx elsewhere was "compatible with MDS but more compatible with CMML/MPD" per MD notes.
10/06 BM Bx "...poor prognosis MDS, best classified as RAEB-2"
11/06 BM Bx "myeloproliferative CMML with leukemic transformation"
(on evaluation for BMT)
12/12/06 Pt was admitted with rapidly progressive disease & was started on chemo to try to get into remission for BMT. Final dx by oncologist is "MPD/CMML with acute myeloid leukemia transformation".
For cases diagnosed prior to 1/1/2010:Code CMML for this case. Code the histology at initial diagnosis. This patient had rapid progression, but the initial diagnosis was "more compatible with CMML/MPD."
For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Reportability/Primary Site--Brain and CNS: Is a chondroma, NOS or a chondroblastoma, NOS that occurs in an intracranial site or along the spinal cord reportable? See Discussion.
In ICD-O-3, chondroma and chondroblastoma are site-associated morphologies for bone. If a chondroma or a chondroblastoma occurs along the spinal cord, is this one of those situations where we can be quite comfortable with a default site to bone and not to spinal cord?
Reference: ICD-O-3; Primary Central Nervous System Tumors, NPCR Training Materials 2004; SINQ 20021152
Chondroma, NOS or chondroblastoma, NOS occuring in intracranial sites or along the spinal cord are not reportable.
Chondroma, NOS and chonroblastoma, NOS are benign tumors of the bone itself, not the intracranial contents.
MP/H Rules--Urinary: How many primaries are abstracted when a patient has a May 2000 invasive papillary transitional cell carcinoma of the bladder, a November 2004 invasive papillary transitional cell carcinoma of the right ureter and a May 2007 urothelial carcinoma in situ of both the left and right ureters?
For cases diagnosed 2007 or later:
Using the pre-2007 multiple primary rules, the PTCC of the bladder in 2000 and the invasive TCC of the right ureter in Nov. 2004 would have been abstracted as separate primaries.
Use the 2007 MP/H rules to evaluate the May 2007 diagnosis. Start with rule M3. Stop at rule M8. The May 2007 diagnosis is the same primary.
Rule M4 does not apply because of the 2000 bladder primary. A clarification will be added to M4 to stress that for the urinary rules, any urinary tumor up to the present point in time is counted when applying this rule.
CS Extension--Prostate: Can the phrase "hard, fixed prostate" be interpreted as clinical extracapsular extension and coded to 50 [extension or fixation to other structures]? See Discussion.
Patient had a "hard, fixed prostate" with needle core bx positive for Gleason grade 4+5=9 adenocarcinoma extensively involving gland. PSA was 87.5. Lymphadenectomy showed 3 positive pelvic/obturator lymph nodes. No prostatectomy was done and no physician TNM staging documented.
Do we need a specific clinical description of other organs to which the prostate is fixed in order to code CS Clinical Extension 50, or does the statement "hard, fixed prostate" qualify? If not, how would we code extension for this seemingly advanced cancer?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Assign extension code 50 [extension or fixation to adjacent structures] based on the term "fixed." Fixation to a particular structure(s) does not have to be specified in order to use code 50.
Do not use the statement "hard" to determine CS extension.
